Frecklington made the move from Lincoln permanent this summer after a loan spell at the end of last season and is confident of making the grade in the Championship.
He said: "I feel as fit as I ever have in my career and I'm so excited about next season.
"I have no idea what the manager's plans are, but obviously I came here to play every week if I can and at as high a level as I possibly can.
"It is a very exciting prospect to think that in a week's time we will be playing at Pride Park in front of a massive crowd.
The dream of occasions like that are what has driven me and are what being a professional footballer is all about.
"I know it is going to be hard, but I'm sure I can make my mark in this side and can continue to improve and raise my game for the Championship in what is going to be a massive season for all of us."
